I am a software tech- Is tricky to configure (Google is your friend!). Highest rated-by far, FAST, "many" small updates, advanced hierusectcs/zero-day (virus like behavior)!!!, good/fast email tech support.
A little more expensive, but once you've been infected using an el-cheapo- you won't think so!
